TUBULAR JOINT FoR BICYCLES.

SPECIFICATION forming part of Letters Patent No. 615,976, dated December13, 1898.

Application filed February 28, 139B- SerialNo. 672,113. (No model.)

T0 at whom it may concern:

Be it known that I, REINHARD FELSOHE, a German subject, residing atMagdeburg, Germany, have invented certain new and useful Improvements inTubular Joints for Bicycles, of which the following is a specification.

My invention relates to tubular joints for bicycles; and its object isto provide a simple, cheap, and durable joint of this kind.

In the accompanying drawings,Figure 1 represents in cross-section partof the frame of a bicycle, showing tubular joints; and Fig. 2 is across-section of a modified form of joint.

Ct represents a part of the frame,- Which is bored out to form a sleeve,as shown, for the reception of the tube 19. It is then still furtherhollowed, and holes are bored through the sides thereof for thereception of molten metal. In the tube b is inserted a tapering hollowferrule 01. The tube and ferrule are then partially collapsed bypressure, so. that there is a space 0 nearly conical in cross-sectionbetween the sleeve and the tube. Into this space the molten metal ispoured, forming a strong and simple joint.

In Fig. 2 is shown a modification in which the sleeve, instead of beinghollowed out, is corrugated.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

A tube-joint for cycles, composed of a perforated sleeve, said sleevebeing hollowed out internally, a tube and an internal ferrule, said tubeand ferrule each having an exterior depression, the tube and sleevebeing so located with respect to each other as to leave a space betweenthem which is wedge-shaped in crosssection, and a filling ofeasily-fusible metal in said space, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

BEINHARD FELSOHE.
